Application filed March 23,

This invention relates to anti-friction bearings and has for an objectto provide a bearing so constructed that when two of these are mountedside by side a predetermined amount of force will be required to clampthem together, this form of construction being for the purpose ofsetting up predetermined .111-

ternal loads in the bearings, which are used among otherthings, forstabihzing rotary parts. v

Reference is made to theaccompanying drawing in which one practicableform of my 'invention is illustrated, in which drawlng Figure 1illustrates inexaggerated proportions one of the bearings made inaccordance with my invention.

Fig. 2 illustrates also in exaggerated proportions a sectional brokenaway view of a pair of bearings loosely assembled, and

Fig. 3 illustrates a pan of my improved bearings in central axialsection and mounted upon a broken away journal or shaft end which isshown in elevation.

Various devices and expedients have been resorted to for initiallyloading taper roller bearings. Most all of these have been dependentupon amounts which are measured by the relative widths of the races of aP5111, of bearings mounted side by side. The present invention is adevelopment of the 1mprovements described in my copendmg appl1 cationfor matchable bearings filed on the twenty-thirdday of March, 1927,bearlng Serial No. 17 7 ,47 8.

A pair of single row roller bearings made in accordance with myinvention are shown in the drawin mounted together in permanent relationorming a single self-contained handling unit. Each of these hearingscomprises an outer race ring, 1, an inner race ring, 2, and a series oftaper rollers, 3. The inner race ring, 2, will be assumed to beofstandard S. A. E. dimensions and the outer ring, 1, to be narroweron theside, 4, than thecorresponding side, 5, of the inner ring by an amountin excess of the S. A. E. tolerance. I propose so manufacturing thesehearings in quantities that it will require the applicationof the sameamount of force to ring this side of the narrower ring into the plane ofthe corresponding side of the wider ring, so that when any two ofthesebearings are indiscriminately or interchangeably placed upon a shaft thewider rings will be clamped DOUBLE-ROW TAPER ROLLER BEARING.

together and the narrower rings caused to meet upon the application ofpredetermined pressure to the narrower rings,-the side face of bothinner rings and of both outer rings meeting on a common plane.

The amount removed or to be removed from the side of 'a'ring isnotmeasured by a certain fixed reduction in the width of the ring onthat side, as compared with the width of the corresponding side of theother ring. but by the pressure or force necessary to bring the groundside of the ring to the planeof the corresponding side of the otherring; lVhen the same side of the similar rings of a pair of bearings arereduced to such an extent that the same pressure is necessary to bringeach of these ground sides to the plane of the corresponding side of theother rin of that bearing then one may be assured that when the membersof this pair are matched or mated the same amount of internal pressureor tightness will be present in both bearings. Any bearing made inaccordance with my invention will match and mate with any other bearinghaving the same size and pressure displacement factor. v

The advantage of this to the user is not only ease in reassembly but thepossibility of replacing one bearing of a pair with another which willfunction correctly.

In the illustration the inner rings of the beari-ngs are shown providedwith race grooves for the rollers or rather with flanges, 11 and 12, attheir respective ends affording the guiding faces for the ends of therollers.

Having described my invention I claim and desire to secure by LettersPatent:

1. A bearing mounting comprising two similar anti-friction bearingsmounted side by side and each comprising an outer race ring, an innerrace ring and a series of taper rollers uniting-these, one of' the ringsof each bearing being narrower on the siddfac the other ring of the samebearing by such an amount that the application of the same amount offorce will be required to bring the respective narrower sides of therings of both bearings into the plane of the corresponding side of thewider rings, and'means for applying a predetermined axial pressure tothe opposite sides of the narrower rings.

2. A bearing mounting comprising two similar taper roller bearingsmounted side by side, the ringshaving plain radial side faces, one ofthe rings of each bearing being narrower on one side than the other ringof the same bearing. by such an amount that the application of the sameamount of force will be required to bring the narrower side of such ringinto the plane of the corresponding side of the wider ring, and meansfor holding the'said narrower sides in engagement, both inner rings andboth outer rings meeting on the same plane.

3. A bearing mounting comprising twosimilar taper roller bearingsmounted side by side, the rings having at't-heir meeting side's plainradial faces, the outer ring of each bearing being narrower at themeeting side-than the inner ring of the same bearing by such an amountthat the application of the same amount of force will be required tobring the narrower 'side of such ring into the plane of thecorresponding side of the inner ring, and means for holding suchnarrower sides in engagement, both inner rings and both outer ringsmeeting on a common plane 4. An anti-friction bearing'comprising anouter race ring, an inner race ring and a series of taper rollersuniting these, one of the said rings being narrower on one side facethan is the other ring of the same hearing by such an amount that theapplication of a predetermined amount of force will be required to bringthe narrower side of the ring into the plane of the corresponding sideof the wider ring.

5. A plurality of similar taper roller bearings, the rings having on oneside plain radial faces, one of the rings of each bearing being narroweron one side than the other rin of the same bearing by such an amount tat the application of the same amount of force will be requiredto bringthe narrower side of such ring into the plane of the corresponding sideof the wider ring.
